Not in this tool. But notice the trees tweaking utility comes with source, including the B3D saving part.
Here I use a feature of copperlicht / webGL that allows to have two textures on one single mesh, whereby the mesh's vertex alpha value determines the visibility of the "top" texture. Additionally Vertex-RGB is used to taint seaground and add diffuse shade under trees.
